Description

Resource allocation method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a resource allocation method and apparatus.

Background

A Reference Signal (RS), which may also be referred to as a "pilot" signal, is a known signal provided by a transmitting end to a receiving end for channel estimation or channel detection. Taking a reference signal as a Sounding Reference Signal (SRS) as an example, the SRS can be used for estimating the uplink channel quality and selecting a channel, calculating a signal to interference plus noise ratio (SINR) of an uplink channel, and also can be used for obtaining an uplink channel coefficient; in a TDD scenario, uplink and downlink channels have mutual difference, and the SRS may also be used to obtain a downlink channel coefficient.

In the existing protocol, a base station configures an SRS resource for a terminal through Radio Resource Control (RRC) signaling, so that the terminal transmits an SRS on the SRS resource. At present, an SRS resource configured by a base station for a terminal must occupy a continuous frequency band in a frequency domain. This results in that the frequency domain resources of SRS may not be suitable for some special scenarios. For example, when there is narrowband interference, a continuous frequency band occupied by SRS resources cannot flexibly avoid the interference bandwidth. As can be seen, the existing SRS frequency domain resource allocation needs to be improved.

Detailed Description

In the description of this application, "/" means "or" unless otherwise stated, for example, A/B may mean A or B. "and/or" herein is merely an association describing an associated object, and means that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. Further, "at least one" means one or more, "a plurality" means two or more. In this application, the words "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

Currently, a base station configures SRS resources for a terminal through Radio Resource Control (RRC) signaling. The RRC signaling may be used to indicate information such as the number of ports (ports) occupied by SRS resources, frequency domain resources, time domain resources, periods, comb, cyclic shift values, and sequence Identifications (IDs).

The frequency domain resources occupied by the SRS resources may be determined by a set of frequency domain parameters in the RRC signaling. For convenience of description, the frequency domain resource occupied by the SRS resource may be referred to as a configuration bandwidth or an SRS frequency domain resource hereinafter.

Specifically, the set of frequency domain parameters includes: n is_RRC、n_shift、B_SRS、C_SRSAnd b_hop。

Wherein, the frequency domain starting position of the SRS resource can be according to n_RRCAnd n_shiftAnd (4) determining.

Number m of Resource Blocks (RBs) occupied by SRS resource_SRS,b′Can be according to b_hop、C_SRSAnd table 1. Wherein m is_SRS,b′B' in (1) is equal to b_hop. For example, suppose b_hop＝0，C_SRSBy looking up table 1, m can be determined as 9_SRS,b′＝32。

Resource block number m occupied by SRS resource on one time domain symbol_SRS,bCan be according to B_SRS、C_SRSAnd table 1. Wherein m is_SRS,bB in (1) is equal to B_SRS. For example, suppose B_SRS＝2，C_SRSBy looking up table 1, m can be determined as 9_SRS,b＝8。

TABLE 1

When b is_hop≥B_SRSThe terminal does not enable the frequency hopping mode. That is, the terminal transmits the SRS in a non-frequency hopping manner. It should be understood that, in the case of adopting the non-frequency hopping manner, the SRS transmitted by the terminal at one time covers the entire configured bandwidth of the SRS resource.

When b is_hop<B_SRSThe terminal enables the frequency hopping mode. That is, the terminal transmits the SRS in a frequency hopping manner. It should be understood that, in the case of the frequency hopping scheme, the SRS transmitted by the terminal each time covers only a part of the configured bandwidth of the SRS resource, and the terminal transmits the SRS multiple times within one frequency hopping period to cover the entire configured bandwidth of the SRS resource.

This is illustrated by way of example in FIG. 1. In fig. 1, one block represents 4 RBs in the frequency domain, so the configured bandwidth of the SRS resource includes 48 RBs, and the number of RBs occupied by the SRS in one time domain symbol is 12, so that the terminal can transmit the SRS in 4 time domain symbols through frequency hopping, and the bandwidth of each time domain symbol is one fourth of the overall configured bandwidth. In fig. 1, the black small squares represent 4 RBs carrying SRS.

In the embodiment of the application, the frequency hopping times of one frequency hopping period is equal to the number of times that the terminal needs to transmit the SRS in one frequency hopping period. Illustratively, the frequency hopping times in fig. 1 are 4.

Optionally, the frequency hopping number is equal to

Wherein N is_bAccording to C_SRSAnd table 1.

For example, suppose b_hop＝0，C_SRS＝9，B_SRSWhen 2, the frequency hopping number is equal to 2 × 2 or 4.

At present, SRS resources configured by a network device for a terminal occupy a continuous band in a frequency domain. Thus, as shown in fig. 2, when there is narrowband interference, the frequency band occupied by the SRS resource cannot flexibly avoid the interference bandwidth. When the interference bandwidth overlaps with the frequency band occupied by the SRS resource, if the terminal transmits the SRS over the interference bandwidth, the transmission power is wasted, and the network device has poor performance of estimating the SRS channel due to the interference. In addition, when the interference bandwidth overlaps with the frequency band occupied by the SRS resource, if the base station only estimates the channel with non-interference bandwidth during channel estimation, it may cause the orthogonality between the code division users to be destroyed and the channel estimation performance to be degraded.

Therefore, how to more flexibly configure the frequency domain resource of the SRS, so that the frequency domain resource of the SRS can be applied to more scenes (for example, scenes with interference bandwidth), is a technical problem to be solved urgently.

In order to solve the foregoing technical problem, embodiments of the present application provide a resource allocation method and apparatus. The technical solution provided in the embodiment of the present application may be applied to various communication systems, for example, a Long Term Evolution (LTE) communication system, a New Radio (NR) communication system using a fifth generation (5th generation, 5G) communication technology, a future Evolution system, or a multiple communication convergence system, and the like. The technical scheme provided by the application can be applied to various application scenarios, for example, scenarios such as machine-to-machine (M2M), macro-micro communication, enhanced mobile internet (eMBB), ultra-reliable and ultra-low latency communication (urlcc), and mass internet of things communication (mtc). These scenarios may include, but are not limited to: communication scenarios between communication devices, network devices, communication scenarios between network devices and communication devices, etc.

As shown in fig. 3, a communication system architecture diagram provided for the embodiment of the present application may include one or more network devices (only one is shown in fig. 3) and one or more terminals connected to each network device.

The network device may be a base station or base station controller for wireless communication, etc. For example, the base station may include various types of base stations, such as: a micro base station (also referred to as a small station), a macro base station, a relay station, an access point, and the like, which are not specifically limited in this embodiment of the present application. In this embodiment, the base station may be an evolved node B (eNB or e-NodeB) in Long Term Evolution (LTE), an eNB in internet of things (IoT) or narrowband internet of things (NB-IoT), a base station in a future 5G mobile communication network or a Public Land Mobile Network (PLMN) in future evolution, which is not limited in this embodiment. In this embodiment of the present application, the apparatus for implementing the function of the network device may be a network device, or may be an apparatus capable of supporting the network device to implement the function, for example, a chip system. In this embodiment of the present application, a device for implementing a function of a network device is taken as an example of a network device, and a technical solution provided in this embodiment of the present application is described.

A network device, such as a base station, generally includes a Base Band Unit (BBU), a Radio Remote Unit (RRU), an antenna, and a feeder for connecting the RRU and the antenna. Wherein, the BBU is used for being responsible for signal modulation. The RRU is responsible for radio frequency processing. The antenna is responsible for the conversion between guided waves on the cable and space waves in the air. On one hand, the length of a feeder line between the RRU and the antenna is greatly shortened by the distributed base station, so that the signal loss can be reduced, and the cost of the feeder line can also be reduced. On the other hand, the RRU and the antenna are smaller, so that the RRU can be installed anywhere, and the network planning is more flexible. Besides RRU remote, BBUs can be centralized and placed in a Central Office (CO), and the centralized mode can greatly reduce the number of base station rooms, reduce the energy consumption of corollary equipment, particularly air conditioners, and reduce a large amount of carbon emission. In addition, after the scattered BBUs are collected and become the BBU baseband pool, unified management and scheduling can be realized, and resource allocation is more flexible. In this mode, all physical base stations evolve into virtual base stations. All virtual base stations share information of data receiving and sending, channel quality and the like of users in a BBU baseband pool, and cooperate with each other to realize joint scheduling.

In some deployments, a base station may include a Centralized Unit (CU) and a Distributed Unit (DU). The base station may also include an Active Antenna Unit (AAU). The CU realizes part of the functions of the base station and the DU realizes part of the functions of the base station. For example, the CU is responsible for processing non-real-time protocols and services, and implementing functions of a Radio Resource Control (RRC) layer and a Packet Data Convergence Protocol (PDCP) layer. The DU is responsible for processing a physical layer protocol and a real-time service, and implements functions of a Radio Link Control (RLC), a Medium Access Control (MAC), and a Physical (PHY) layer. The AAU implements part of the physical layer processing functions, radio frequency processing and active antenna related functions. Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, the higher layer signaling, such as RRC layer signaling or PDCP layer signaling, can also be considered to be sent by the DU or from the DU + AAU under this architecture. It is to be understood that the network device may be a device comprising one or more of a CU node, a DU node, an AAU node. In addition, a CU may be divided into network devices in the RAN, and may also be divided into network devices in a Core Network (CN), which is not limited herein.

The terminal is a device with wireless transceiving function. The terminal can be deployed on land, including indoors or outdoors, hand-held or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal device may be a User Equipment (UE). Wherein the UE comprises a handheld device, an in-vehicle device, a wearable device, or a computing device with wireless communication capabilities. Illustratively, the UE may be a mobile phone (mobile phone), a tablet computer, or a computer with wireless transceiving function. The terminal device may also be a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in smart grid, a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and so on. In the embodiment of the present application, the apparatus for implementing the function of the terminal may be the terminal, or may be an apparatus capable of supporting the terminal to implement the function, such as a chip system. In the embodiment of the present application, the chip system may be composed of a chip, and may also include a chip and other discrete devices. In the embodiment of the present application, a device for implementing a function of a terminal is taken as an example, and a technical solution provided in the embodiment of the present application is described.

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

As shown in fig. 5, a resource allocation method provided in this embodiment of the present application includes the following steps:

s101, the network equipment generates SRS resource configuration information.

The SRS resource configuration information may be used to configure one SRS resource.

In this embodiment of the present application, the SRS resource configuration information includes N sets of frequency domain parameters, where N is a positive integer greater than 1.

It is to be appreciated that the set of frequency domain parameters in the SRS resource configuration information can include different parameters in different communication systems. The embodiment of the present application does not limit specific parameters included in a set of frequency domain parameters.

For example, taking the application of the embodiments of the present application to the NR system as an example, the set of frequency domain parameters may include: a frequency domain position parameter, a frequency domain offset parameter, a symbol bandwidth parameter,A bandwidth aggregation parameter, and a configuration bandwidth parameter. Wherein the frequency domain position parameter may be n as mentioned above_RRCThe frequency domain offset parameter may be n as mentioned above_shiftThe symbol bandwidth parameter may be B as mentioned above_SRSThe bandwidth aggregation parameter may be C as mentioned above_SRSThe configured bandwidth parameter may be b mentioned above_hop。n_RRC、n_shift、B_SRS、C_SRSAnd b_hopReference is made to the description of the prior art and no further description is given here.

In an alternative embodiment, the configuration information may include one or more of: freqDomainPosition-configuration n_RRCfreqDomainShift parameter-configuration n_shiftfreqHopping parameter-configuration B_SRS、C_SRSOr b_hopOne or more of the parameters.

It should be understood that the names of the frequency domain location parameter, the frequency domain offset parameter, the symbol bandwidth parameter, the bandwidth aggregation parameter, and the configuration bandwidth parameter described above are merely examples. The frequency domain parameters may have different names in different communication systems.

In an embodiment of the present application, a set of frequency domain parameters is used to determine one frequency domain sub-resource of the SRS resource in the frequency domain. One frequency domain sub-resource is a part of the frequency domain resource occupied by the SRS resource. The frequency domain sub-resources may have other names, such as sub-frequency bands, and the like, and the embodiments of the present application do not limit this.

One frequency domain sub-resource occupies one or more frequency domain units in the frequency domain. The number of frequency domain units occupied by a frequency domain sub-resource in the frequency domain may be determined by a set of frequency domain parameters corresponding to the frequency domain sub-resource. Further, in the NR system, a frequency-domain sub-resource occupies the number of frequency-domain units in the frequency domain according to C in a set of frequency-domain parameters corresponding to the frequency-domain sub-resource_SRSAnd b_hopTo be determined.

Optionally, the frequency domain unit refers to a Resource Block (RB). One resource block may be composed of a plurality of subcarriers. For example, in the case where the subcarrier spacing is 15kHz, one RB may include 12 subcarriers.

The N sets of frequency domain parameters correspond to the N frequency domain sub-resources one to one. It should be understood that the frequency domain resource occupied by the SRS resource may be composed of the N frequency domain sub-resources. Therefore, the bandwidth of the frequency domain resource occupied by the SRS resource is the sum of the bandwidths of the N frequency domain sub-resources.

In the embodiment of the present application, the N frequency domain sub-resources do not overlap and are not consecutive in the frequency domain.

It should be understood that the N frequency domain sub-resources do not overlap and are discontinuous in the frequency domain, specifically: any two of the N frequency domain sub-resources are non-overlapping and non-contiguous in the frequency domain.

For any two frequency domain sub-resources of the N frequency domain sub-resources, the two frequency domain sub-resources are not overlapped in the frequency domain, which means that the two frequency domain sub-resources do not occupy the same frequency domain unit in the frequency domain.

For example, suppose that frequency domain sub-resource #1 occupies RB #1-RB #5, and frequency domain sub-resource #2 occupies RB #4-RB # 10. Since frequency domain sub-resource #1 and frequency domain sub-resource #2 both occupy RB #4 and RB #5, it can be determined that there is a partial overlap of frequency domain sub-resource #1 and frequency domain sub-resource #2 in the frequency domain.

For another example, suppose that frequency domain sub-resource #1 occupies RB #1-RB #5, and frequency domain sub-resource #2 occupies RB #6-RB # 10. Since frequency domain sub-resource #1 and frequency domain sub-resource #2 do not occupy the same RB, frequency domain sub-resource #1 and frequency domain sub-resource #2 do not overlap in the frequency domain.

For any two frequency domain sub-resources of the N frequency domain sub-resources, the two frequency domain sub-resources are discontinuous in the frequency domain, which means that the last frequency domain unit occupied by one frequency domain sub-resource in the frequency domain is not adjacent to the first frequency domain unit occupied by another frequency domain sub-resource in the frequency domain.

For example, suppose that frequency domain sub-resource #1 occupies RB #1-RB #5, and frequency domain sub-resource #2 occupies RB #6-RB # 10. The last RB occupied by frequency domain sub-resource #1 is RB #5, and the first RB occupied by frequency domain sub-resource #2 is RB # 6. Since RB #5 and RB #6 are adjacent, frequency domain sub-resource #1 and frequency domain sub-resource #2 are contiguous in the frequency domain.

For another example, suppose that frequency domain sub-resource #1 occupies RB #1-RB #5, and frequency domain sub-resource #2 occupies RB #7-RB # 10. The last RB occupied by frequency domain sub-resource #1 is RB #5, and the first RB occupied by frequency domain sub-resource #2 is RB # 7. Since RB #5 and RB #7 are not adjacent, frequency domain sub-resource #1 and frequency domain sub-resource #2 are not contiguous.

Optionally, the frequency domain units occupied by the frequency domain sub-resources may be sorted in order from low frequency to high frequency. In this case, the first frequency domain unit in the frequency domain sub-resources is the frequency domain unit with the lowest frequency in the frequency domain sub-resources, and the last frequency domain unit in the frequency domain sub-resources is the frequency domain unit with the highest frequency in the frequency domain sub-resources.

Optionally, the frequency domain units occupied by the frequency domain sub-resources may be ordered from high frequency to low frequency. In this case, the first frequency domain unit in the frequency domain sub-resources is the frequency domain unit with the highest frequency in the frequency domain sub-resources, and the last frequency domain unit in the frequency domain sub-resources is the frequency domain unit with the lowest frequency in the frequency domain sub-resources.

Optionally, to avoid interference of the interference bandwidth, the N frequency domain sub-resources are not overlapped with the interference bandwidth. That is, for any one of the N frequency domain sub-resources, the frequency domain sub-resource and the interference bandwidth do not occupy the same frequency domain unit in the frequency domain.

It should be understood that the network device may first determine the locations of the N frequency domain sub-resources in the frequency domain; then, for any frequency domain sub-resource in the N frequency domain sub-resources, the network device determines a set of frequency domain parameters corresponding to the frequency domain sub-resources according to the position of the frequency domain sub-resource in the frequency domain.

Optionally, the SRS resource configuration information may include other configuration parameters besides the N sets of frequency domain parameters. For example, the SRS resource configuration information may further include time domain parameters, code domain parameters, and the like.

S102, the network equipment sends SRS resource configuration information to the terminal. Correspondingly, the terminal receives the SRS resource configuration information sent by the network device.

Optionally, the SRS resource configuration information may be carried in RRC signaling.

S103, the terminal determines SRS resources according to the SRS resource configuration information.

As a possible implementation manner, the terminal determines N frequency domain sub-resources of the SRS resource in the frequency domain according to N sets of frequency domain parameters in the SRS resource configuration information.

Based on the technical scheme shown in fig. 5, compared with the prior art that SRS resources configured by SRS resource configuration information can only occupy a continuous band in the frequency domain, the SRS resource configuration information provided in the embodiment of the present application includes N sets of frequency domain parameters, so that the SRS resources occupy N frequency domain sub-resources in the frequency domain, and the N frequency domain sub-resources are not overlapped and discontinuous, so that the SRS resources can be more flexible in the frequency domain to adapt to different application scenarios (for example, scenarios with interference bandwidth).

Optionally, on the basis of the embodiment shown in fig. 5, as shown in fig. 6, the resource allocation method further includes steps S104 to S105.

S104, the terminal sends SRS to the network equipment on the SRS resource.

The SRS time domain transmission method includes: periodic transmission, semi-persistent transmission, and aperiodic transmission.

And when the time domain transmission mode configured by the SRS resource configuration information is periodic transmission, the terminal periodically transmits the SRS on the SRS resource after receiving the SRS resource configuration information.

When the time domain transmission mode configured by the SRS resource configuration information is semi-persistent transmission, the terminal periodically transmits the SRS on the SRS resource after receiving the MAC layer signaling for activating the semi-persistent transmission.

When the time domain transmission mode configured by the SRS resource configuration information is aperiodic transmission, the terminal transmits the SRS on the SRS resource after receiving the DCI signaling for activating the aperiodic transmission.

In the embodiment of the present application, the terminal may transmit the SRS on the SRS resource in a frequency hopping manner. Or, the terminal may transmit the SRS in a non-frequency hopping manner on the SRS resource.

Optionally, whether the terminal transmits the SRS in a frequency hopping manner depends on whether at least one set of frequency domain parameters in the N sets of frequency domain parameters meets a preset condition. That is, when at least one set of frequency domain parameters in the N sets of frequency domain parameters meets the preset condition, the terminal transmits the SRS in a frequency hopping manner. Or, when the N sets of frequency domain parameters do not meet the preset condition, the terminal transmits the SRS in a non-frequency hopping manner.

Optionally, for a set of frequency domain parameters, the preset condition is: b_hopIs less than B_SRS。

Optionally, when the terminal transmits the SRS on the SRS resource in a frequency hopping manner, the frequency hopping number of the SRS in one frequency hopping period is equal to the sum of the frequency hopping numbers determined by each set of frequency domain parameters in the N sets of frequency domain parameters.

Illustratively, the number of hops in a hop period of the SRS is equal to

It should be understood that,

the number of hops determined for the nth set of frequency domain parameters.

Wherein N is a positive integer greater than or equal to 1 and less than or equal to N. B is_SRS,nFor the symbol bandwidth parameter in the nth set of frequency domain parameters in the SRS resource configuration information, b_hop,nIs the configuration bandwidth parameter in the nth set of frequency domain parameters in the SRS resource configuration information. N is a radical of_b,nAccording to C_SRS,nAnd b are determined by looking up table 1. C_SRS,nAnd configuring the bandwidth aggregation parameters in the nth set of frequency domain parameters in the information for the SRS resource.

For example, the SRS resource configuration information includes 2 sets of frequency domain parameters. Wherein C is in the first set of frequency domain parameters_SRS＝9，B_SRS＝2，b_hop1. Thus, based on table 1, the number of hops determined by the first set of frequency domain parameters is equal to 2. C in the second set of frequency domain parameters_SRS＝9，B_SRS＝2，b_hop0. Thus, based on table 1, the number of hops determined by the second set of frequency domain parameters is equal to 4. Therefore, the number of hopping frequencies of the SRS within one hopping period is equal to 6.

Optionally, the terminal transmits the SRS on the SRS resource in a frequency hopping manner, which may adopt the following one or two manners. The first method may be referred to as an individual frequency hopping method, and the second method may be referred to as an overall frequency hopping method.

In the first mode, the terminal determines the arrangement sequence of the N frequency domain sub-resources. And then, the terminal sequentially transmits the SRS on the N frequency domain sub-resources in a frequency hopping manner according to the arrangement sequence of the N frequency domain sub-resources.

For example, the terminal sequentially transmits the SRS over the N frequency-domain sub-resources in a frequency hopping manner according to the permutation order of the N frequency-domain sub-resources, which may include the following steps S10-S13.

S10, setting i equal to 0.

S11, the terminal transmits the SRS in the i-th frequency domain sub-resource by frequency hopping.

Based on step S11, the SRS may cover the entire ith frequency domain sub-resource.

S12, setting i ═ i + 1.

S13, when i is less than or equal to N, executing the step S11; when i > N, step S10 is performed.

Illustratively, referring to fig. 7, the SRS resource configuration information includes two sets of frequency domain parameters, a first set of frequency domain parameters corresponding to frequency domain sub-resource #1, and a second set of frequency domain sub-resources corresponding to frequency domain sub-resource # 2. In one hopping period, the terminal first transmits the SRS on the frequency domain sub-resource #1 in a frequency hopping manner. After that, the terminal transmits the SRS on the frequency domain sub-resource #2 in a frequency hopping manner.

Optionally, the terminal determines the arrangement order of the N frequency domain sub-resources, and may adopt any one of the following manners:

(1) when the SRS resource configuration information further includes the index of each of the N sets of frequency domain parameters, the terminal determines the arrangement order of the N frequency domain sub-resources according to the index of each of the N sets of frequency domain parameters.

In one possible design, the terminal arranges the N sets of frequency domain parameters in order of decreasing index to increasing index, and determines the arrangement order of the N sets of frequency domain parameters. Because the N sets of frequency domain parameters correspond to the N frequency domain sub-resources one to one, the terminal can determine the arrangement order of the N frequency domain sub-resources according to the arrangement order of the N sets of frequency domain parameters.

Based on the design, the smaller the index, the smaller the sequence number of the frequency domain sub-resources corresponding to a set of frequency domain parameters in the ranking order.

For example, the SRS resource configuration information includes 3 sets of frequency domain parameters, a first set of frequency domain parameters corresponding to frequency domain sub-resource #1, a second set of frequency domain parameters corresponding to frequency domain sub-resource #2, and a third set of frequency domain parameters corresponding to frequency domain sub-resource # 3. The index corresponding to the first set of frequency domain parameters is 2, the index corresponding to the second set of frequency domain parameters is 3, and the index corresponding to the third set of frequency domain parameters is 1, so that the 3 sets of frequency domain parameters are arranged in the order of the indexes from small to large, specifically: a third set of frequency domain parameters, a first set of frequency domain parameters, and a second set of frequency domain parameters. Based on this, the arrangement order of the 3 frequency domain sub-resources is: frequency domain sub-resource #3, frequency domain sub-resource #1, and frequency domain sub-resource # 2. That is, the sequence number of the frequency domain sub-resource #3 in the arrangement order is 1, the sequence number of the frequency domain sub-resource #1 in the arrangement order is 2, and the sequence number of the frequency domain sub-resource #2 in the arrangement order is 3.

In another possible design, the terminal arranges the N sets of frequency domain parameters in the order from large to small according to the indexes, and determines the arrangement order of the N sets of frequency domain parameters. Because the N sets of frequency domain parameters correspond to the N frequency domain sub-resources one to one, the terminal can determine the arrangement order of the N frequency domain sub-resources according to the arrangement order of the N sets of frequency domain parameters.

Based on the design, the larger the index is, the smaller the sequence number of the frequency domain sub-resources corresponding to a set of frequency domain parameters in the arrangement order is.

(2) And the terminal determines the arrangement sequence of the N frequency domain sub-resources according to the frequencies of the N frequency domain sub-resources.

In one possible design, the terminal arranges the N frequency domain sub-resources in order from high to low in frequency, and determines an arrangement order of the N frequency domain sub-resources.

Based on this design, the higher frequency sub-resources have smaller sequence numbers in the ranking order.

For example, the SRS resource configuration information includes 3 sets of frequency domain parameters, a first set of frequency domain parameters corresponding to frequency domain sub-resource #1, a second set of frequency domain parameters corresponding to frequency domain sub-resource #2, and a third set of frequency domain parameters corresponding to frequency domain sub-resource # 3. The 3 frequency sub-resources are arranged in the order of frequency from high to low: frequency domain sub-resource #3, frequency domain sub-resource #1, and frequency domain sub-resource # 2. That is, the sequence number of the frequency domain sub-resource #3 in the arrangement order is 1, the sequence number of the frequency domain sub-resource #1 in the arrangement order is 2, and the sequence number of the frequency domain sub-resource #2 in the arrangement order is 3.

In another possible design, the terminal arranges the N frequency domain sub-resources in order from low to high frequency, and determines an arrangement order of the N frequency domain sub-resources.

Based on this design, the higher the frequency, the larger the number of frequency sub-resources in the ranking order.

And secondly, the terminal determines the frequency hopping pattern according to the N groups of frequency domain parameters. Then, the terminal transmits the SRS on the SRS resource in a frequency hopping manner according to the frequency hopping pattern.

Alternatively, the hopping pattern may be determined according to the following: for the ith frequency domain sub-resource in the N frequency domain sub-resources, the terminal determines the frequency hopping times P corresponding to the ith frequency domain sub-resource according to the ith group of frequency domain parameters_i(ii) a Then, the terminal according to the frequency hopping times P corresponding to the ith frequency domain sub-resource_iDividing the ith frequency domain sub-resource into P_iAnd (4) sub-bands. In this way, the N frequency domain sub-resources may be divided into P sub-bands,

then, the terminal generates a frequency hopping pattern according to the P subbands.

In a possible design, when the frequency hopping times corresponding to the N frequency domain sub-resources are the same, the terminal may arrange the P subbands according to a tree structure to generate a frequency hopping pattern.

Exemplarily, referring to fig. 8(a), the SRS resource configuration information includes two sets of frequency domain parameters, a first set of frequency domain parameters corresponding to frequency domain sub-resource #1, and a second set of frequency domain sub-resources corresponding to frequency domain sub-resource # 2. The frequency hopping times determined by the first set of frequency domain parameters is 2 and the frequency hopping times determined by the second set of frequency domain parameters is 2. Here, frequency domain sub-resource #1 may be divided into sub-band #1 and sub-band #2, and frequency domain sub-resource #2 may be divided into sub-band #3 and sub-band # 4. The sub-bands #1 to #4 are arranged in a tree structure. Thus, at the first transmission opportunity, the terminal transmits the SRS on subband # 1. In the second transmission opportunity, the terminal transmits the SRS on subband # 3. In a third transmission opportunity, the terminal transmits SRS on subband # 2. At a fourth transmission opportunity, the terminal transmits SRS on subband # 4.

In a frequency hopping period, one transmission opportunity is the time domain resource used when the terminal transmits the SRS in a frequency hopping manner once. For example, the time domain unit may be an Orthogonal Frequency Division Multiplexing (OFDM) symbol or a slot.

It should be appreciated that the number of transmission opportunities within a hop period is equal to the number of hops of a hop period. In one frequency hopping period, the SRSs transmitted at different transmission occasions occupy different sub-bands.

In another possible design, when the frequency hopping times corresponding to the N frequency domain sub-resources are different, the terminal may arrange the P subbands according to a preset rule to generate a frequency hopping pattern. Wherein the preset rule is used for enabling the P sub-bands to be distributed discretely.

Optionally, the preset rule may be configured in the terminal and the network device in advance. The preset rule may be specified by a communication protocol. Alternatively, the preset rule may be determined by mutual negotiation between the terminal and the network device.

Illustratively, referring to fig. 8(b), the SRS resource configuration information includes two sets of frequency domain parameters, a first set of frequency domain parameters corresponding to frequency domain sub-resource #1, and a second set of frequency domain sub-resources corresponding to frequency domain sub-resource # 2. The frequency hopping times determined by the first set of frequency domain parameters is 2 and the frequency hopping times determined by the second set of frequency domain parameters is 4. Where frequency domain sub-resource #1 may be divided into sub-band #1-1 and sub-band #1-2, and frequency domain sub-resource #2 may be divided into sub-band #2-1, sub-band 2-2, sub-band 2-3, and sub-band # 2-4. And the sub-bands are arranged according to a preset rule to generate frequency hopping patterns. Thus, at a first transmission opportunity, the terminal transmits SRS on subband # 1-1; in a second transmission opportunity, the terminal transmits the SRS in the sub-band # 2-1; in a third transmission opportunity, the terminal transmits the SRS in the sub-band # 1-2; in a fourth transmission opportunity, the terminal transmits the SRS in the sub-band # 2-2; in a fifth transmission opportunity, the terminal transmits the SRS in the sub-band # 2-3; in the sixth transmission opportunity, the terminal transmits the SRS in subband # 2-4.

Based on the second mode, L groups of sending opportunities exist in one frequency hopping period to meet a preset condition, any one group of sending opportunities in the L groups of sending opportunities comprises two adjacent sending opportunities, and the preset condition is as follows: sub-bands occupied by the SRSs transmitted at two adjacent transmission occasions respectively belong to different frequency domain sub-resources in the N frequency domain sub-resources, and L is a positive integer greater than or equal to N.

Taking fig. 8(a) as an example, in one frequency hopping period, the SRS transmitted at the first transmission opportunity occupies subband #1, and the SRS transmitted at the second transmission opportunity occupies subband #2, and since subband #1 and subband #2 belong to different frequency domain sub-resources, the first transmission opportunity and the second transmission opportunity constitute a set of transmission opportunities satisfying a preset condition.

In fig. 8(a), there are 3 sets of transmission opportunities within one hop period that satisfy the preset condition. The 3 sets of transmission timings are { first transmission timing, second transmission timing }, { second transmission timing, third transmission timing }, and { third transmission timing, fourth transmission timing }, respectively.

It should be understood that, by using the frequency hopping mode of the second mode, the network device can be ensured to quickly acquire channel information in a wider frequency domain, which is beneficial for the network device to quickly acquire channel information in a full bandwidth. Taking fig. 8(a) as an example, the network device obtains the channel information of subband #1 and subband #3 after two frequency hops, and subband #1 and subband #3 are distributed and dispersed over the whole bandwidth, which is beneficial for the network device to estimate the channel information of the whole bandwidth through interpolation or extrapolation, etc.

S105, the network equipment receives the SRS sent by the terminal on the SRS resource.

It should be appreciated that when the terminal transmits the SRS in a frequency-hopping manner on the SRS resources, the network device receives the SRS in a frequency-hopping manner on the SRS resources. Or, when the terminal transmits the SRS on the SRS resource in the non-frequency-hopping manner, the network device receives the SRS on the SRS resource in the non-frequency-hopping manner.

Optionally, the network device receives the SRS on the SRS resource in a non-frequency hopping manner, which may adopt the following one or two manners.

In a first mode, the network device determines the arrangement sequence of the N frequency domain sub-resources. And then, the network equipment sequentially receives the SRS sent by the terminal in a frequency hopping mode on the N frequency domain sub-resources according to the arrangement sequence of the N frequency domain sub-resources.

And secondly, the network equipment determines the frequency hopping pattern according to the N groups of frequency domain parameters. Then, the network device transmits the SRS in a frequency hopping manner on the SRS resource by the receiving terminal according to the frequency hopping pattern.

For details of the first and second manners, reference may be made to the related description in step S104, and details are not repeated here.

Based on the technical solution shown in fig. 6, under the condition that one SRS resource occupies N frequency domain sub-resources in the frequency domain, the terminal may transmit the SRS on the N frequency domain sub-resources, so that the network device may perform channel estimation on the N frequency domain sub-resources.

As shown in fig. 9, a resource allocation method provided in this embodiment of the present application includes the following steps:

s201, the network equipment generates M pieces of SRS resource configuration information.

In the embodiment of the present application, the SRS resource configuration information is used to configure one SRS resource. Therefore, the M SRS resource configuration information corresponds to the M SRS resources one to one. M is a positive integer greater than 1.

For any SRS resource configuration information in the M SRS resource configuration information, one SRS resource configuration information includes a set of frequency domain parameters, and the set of frequency domain parameters is used to determine the frequency domain resources occupied by the SRS resources in the frequency domain.

For example, taking the application of the embodiments of the present application to the NR system as an example, the set of frequency domain parameters may include: a frequency domain location parameter, a frequency domain offset parameter, a symbol bandwidth parameter, a bandwidth aggregation parameter, and a configuration bandwidth parameter. Wherein the frequency domain position parameter may be n as mentioned above_RRCFrequency domain offsetThe parameter may be n as mentioned above_shiftThe symbol bandwidth parameter may be B as mentioned above_SRSThe bandwidth aggregation parameter may be C as mentioned above_SRSThe configured bandwidth parameter may be b mentioned above_hop。n_RRC、n_shift、B_SRS、C_SRSAnd b_hopReference is made to the description of the prior art and no further description is given here.

In an alternative embodiment, the set of frequency domain parameters may include one or more of: freqDomainPosition-configuration n_RRCfreqDomainShift parameter-configuration n_shiftfreqHopping parameter-configuration B_SRS、C_SRSOr b_hopOne or more of the parameters.

In the embodiment of the present application, the M SRS resources do not overlap and are not consecutive in the frequency domain.

It should be understood that the M SRS resources do not overlap and are discontinuous in the frequency domain, specifically: any two SRS resources of the M SRS resources do not overlap and are discontinuous in the frequency domain.

For any two SRS resources in the M SRS resources, the two SRS resources do not overlap in the frequency domain, specifically: the two SRS resources do not occupy the same frequency domain unit in the frequency domain.

For example, assume that SRS resource #1 occupies RB #1-RB #5, and SRS resource #2 occupies RB #4-RB # 10. Since both SRS resource #1 and SRS resource #2 occupy RB #4 and RB #5, it can be determined that there is a partial overlap in the frequency domain between SRS resource #1 and SRS resource # 2.

For another example, assume that SRS resource #1 occupies RB #1-RB #5, and SRS resource #2 occupies RB #6-RB # 10. Since SRS resource #1 and SRS resource #2 do not occupy the same RB, SRS resource #1 and SRS resource #2 do not overlap in the frequency domain.

For any two SRS resources in the M SRS resources, the two SRS resources are discontinuous in the frequency domain, specifically: the last frequency domain unit occupied by one SRS resource in the frequency domain is not adjacent to the first frequency domain unit occupied by another SRS resource in the frequency domain.

For example, assume that SRS resource #1 occupies RB #1-RB #5, and SRS resource #2 occupies RB #6-RB # 10. The last RB occupied by SRS resource #1 is RB #5, and the first RB occupied by SRS resource #2 is RB # 6. Since RB #5 and RB #6 are adjacent, SRS resource #1 and SRS resource #2 are contiguous in the frequency domain.

For another example, assume that SRS resource #1 occupies RB #1-RB #5, and SRS resource #2 occupies RB #7-RB # 10. The last RB occupied by SRS resource #1 is RB #5, and the first RB occupied by SRS resource #2 is RB # 7. Since RB #5 and RB #7 are not adjacent, SRS resource #1 and SRS resource #2 are not contiguous.

Optionally, the frequency domain units occupied by the SRS resources may be sorted in order from low frequency to high frequency. In this case, the first frequency domain unit in the SRS resource is the frequency domain unit with the lowest frequency in the SRS resource, and the last frequency domain unit in the SRS resource is the frequency domain unit with the highest frequency in the SRS resource.

Optionally, the frequency domain units occupied by the SRS resources may be sorted in order from a high frequency to a low frequency. In this case, the first frequency domain unit in the SRS resource is the frequency domain unit with the highest frequency in the SRS resource, and the last frequency domain unit in the SRS resource is the frequency domain unit with the lowest frequency in the SRS resource.

Optionally, to avoid the influence of the interference bandwidth, the M SRS resources do not overlap with the interference bandwidth in the frequency domain. That is, any SRS resource in the M SRS resources does not occupy the same frequency domain unit as the interference bandwidth in the frequency domain.

In the embodiment of the present application, M SRS resources are associated with the same antenna port. It should be understood that the antenna ports described above are SRS ports. Since the M SRS resources are associated with the same antenna port, the channel parameters of the M SRS resources can be shared, so that the SRS transmitted on the M SRS resources can jointly perform channel estimation. The channel reference may be a large scale coefficient, delay spread, beam direction, etc.

In one possible design, the network device indicates, in an implicit manner, that M SRS resources are associated with the same antenna port to the terminal.

In another possible design, the network device indicates, in an explicit manner, to the terminal that M SRS resources are associated with the same antenna port. For example, the network device sends indication information to the terminal, where the indication information is used to indicate that the M SRS resources are associated with the same antenna port. It should be understood that the above indication information may be transmitted together with the M SRS resource configuration information. Alternatively, the indication information may be transmitted separately.

Optionally, the M SRS resource configuration information includes the same time domain parameter. The time domain parameter may be a period and/or a time domain offset value.

Optionally, the comb, the cyclic shift value, and/or the sequence ID used by the M SRS resources may be the same or different, which is not limited in this embodiment of the present application.

S202, the network equipment sends M pieces of SRS resource configuration information to the terminal. Correspondingly, the terminal receives the M SRS resource configuration information sent by the network device.

Optionally, the M SRS resource configuration information may be carried in RRC signaling.

It should be understood that the M SRS resource configuration information may be transmitted simultaneously or separately.

It should be understood that the M SRS resource configuration information may be encapsulated in the same signaling or may be encapsulated in different signaling.

S203, the terminal determines M SRS resources according to the M SRS resource configuration information.

Based on the embodiment shown in fig. 9, the network device sends M SRS resource configuration information to the terminal to configure M SRS resources. Since the M SRS resources are associated with the same antenna port, the SRS transmitted on the M SRS resources can jointly perform channel estimation. And the M SRS resources are not overlapped and discontinuous in the frequency domain, so that the frequency domain resources of the SRS are more flexibly configured to adapt to different application scenarios (for example, scenarios with interference bandwidth).

Optionally, on the basis of the embodiment shown in fig. 9, as shown in fig. 10, the resource allocation method further includes step S204.

S204, the terminal sends the SRS on the M SRS resources.

When the time domain transmission mode of the M SRS resources is periodic transmission, the terminal periodically transmits the SRS on the M SRS resources after receiving the M SRS resource configuration information.

When the time domain transmission mode of the M SRS resources is semi-persistent transmission, the terminal periodically transmits the SRS on the M SRS resources after receiving the MAC layer signaling for activating the semi-persistent transmission.

When the time domain transmission mode of the M SRS resources is aperiodic transmission, the terminal receives the DCI signaling for activating the aperiodic transmission, and then transmits the SRS on the M SRS resources.

In the embodiment of the present application, the terminal may transmit the SRS on the M SRS resources in a frequency hopping manner. Or, the terminal may transmit the SRS on the M SRS resources in a non-frequency hopping manner.

Optionally, whether the terminal transmits the SRS in a frequency hopping manner depends on whether at least one SRS resource configuration information exists in the M SRS resource configuration information and meets a preset condition. That is, when at least one SRS resource configuration information of the M SRS resource configuration information satisfies the preset condition, the terminal transmits the SRS in a frequency hopping manner. Or, when none of the M SRS resource configuration information satisfies the preset condition, the terminal transmits the SRS in a non-frequency hopping manner.

For example, in the NR system, for one SRS resource configuration information, the preset condition is: b_hopIs less than B_SRS。

Optionally, when the terminal transmits the SRS on the M SRS resources in a frequency hopping manner, the frequency hopping number of the SRS in one frequency hopping period is equal to the sum of the frequency hopping numbers corresponding to the M SRS resources. It should be understood that the frequency hopping number corresponding to one SRS resource is determined according to the SRS resource configuration information corresponding to the SRS resource.

Illustratively, the number of hops in a hop period of the SRS is equal to

It should be understood that,

and the frequency hopping times determined by the mth SRS resource configuration information.

Wherein M is a positive integer of 1 to M. B is_SRS,mConfiguring a symbol bandwidth parameter in information for the mth SRS resource, b_hop,mAnd configuring bandwidth parameters in the mth SRS resource configuration information. N is a radical of_b,mAccording to C_SRS,mAnd b are determined by looking up table 1. C_SRS,mAnd configuring a bandwidth aggregation parameter in the information for the mth SRS resource.

For example, the network device sends 2 SRS resource configuration information to the terminal. Wherein, C in the first SRS resource configuration information_SRS＝9，B_SRS＝2，b_hop1. Therefore, based on table 1, the number of frequency hops determined by the first SRS resource configuration information is equal to 2. Second SRS resource configuration information C_SRS＝9，B_SRS＝2，b_hop0. Therefore, based on table 1, the number of frequency hops determined by the second SRS resource configuration information is equal to 4. Therefore, the number of hopping frequencies of the SRS within one hopping period is equal to 6.

Optionally, the terminal transmits the SRS on the M SRS resources in a frequency hopping manner, and may adopt the following one or two manners. The first mode may also be referred to as an individual frequency hopping mode. The second scheme may also be referred to as a global hopping scheme.

In a first mode, the terminal determines the arrangement sequence of M SRS resources. And then, the terminal transmits the SRS in a frequency hopping mode on the M SRS resources in sequence according to the arrangement sequence of the M SRS resources.

Illustratively, the terminal sequentially transmits the SRS on the M SRS resources in a frequency hopping manner according to the arrangement order of the M SRS resources, including the following steps S20-S23.

S20, setting i equal to 0.

S21, the terminal transmits SRS on the ith SRS resource in a frequency hopping manner.

Based on step S21, the SRS may cover the frequency domain resource occupied by the entire ith SRS resource.

S22, setting i ═ i + 1.

S23, when i is less than or equal to N, executing the step S21; when i > N, step S20 is performed.

Exemplarily, referring to fig. 11, a network device transmits SRS resource configuration information #1 and SRS resource configuration information #2 to a terminal, where the SRS resource configuration information #1 is used for determining an SRS resource #1, and the SRS resource configuration information #2 is used for determining an SRS resource # 2. In the primary hopping period, the terminal first transmits the SRS in the SRS resource #1 by hopping. After that, the terminal transmits the SRS in the SRS resource #2 by frequency hopping.

Optionally, the terminal determines the arrangement order of the M SRS resources, and may adopt any one of the following manners:

(1) when the SRS resource configuration information further includes the index of the SRS resource, the terminal determines the arrangement order of the M SRS resources according to the index of each of the M SRS resources.

In one possible design, the terminal arranges the M SRS resources in order from small to large according to the indexes of the SRS resources, and determines the arrangement order of the M SRS resources.

Based on this design, the SRS resource with smaller index has smaller sequence number in the ranking order.

In another possible design, the terminal arranges the M SRS resources according to a sequence of SRS resource indexes from large to small, and determines an arrangement sequence of the M SRS resources.

Based on this design, the SRS resources with smaller indexes have larger sequence numbers in the ranking order.

(2) And the terminal determines the arrangement sequence of the M SRS resources according to the frequencies of the M SRS resources.

It should be understood that the frequency of the SRS resource is the frequency of the frequency domain resource occupied by the SRS resource in the frequency domain.

In one possible design, the terminal arranges the M SRS resources in the order of the frequencies from low to high, and determines the arrangement order of the M SRS resources.

Based on this design, the lower the frequency, the smaller the number of SRS resources in the ranking order.

In another possible design, the terminal arranges the M SRS resources in the order of frequencies from high to low, and determines the arrangement order of the M SRS resources.

Based on this design, the higher frequency SRS resources have smaller sequence numbers in the ranking order.

And secondly, the terminal determines a frequency hopping pattern according to the M pieces of SRS resource configuration information. Then, the terminal transmits the SRS on the M SRS resources in a frequency hopping manner according to the frequency hopping pattern.

Alternatively, the hopping pattern may be determined according to the following: for the ith SRS resource in the M SRS resources, the terminal determines the frequency hopping times P corresponding to the ith SRS resource according to the ith SRS resource configuration information_i(ii) a Then, the terminal hops the number of times P according to the ith SRS resource_iDividing the frequency domain resource occupied by the ith SRS resource into P_iAnd (4) sub-bands. In this way, the terminal can determine P subbands,

In one possible design, when the number of frequency hopping times corresponding to the M SRS resources is the same, the terminal may arrange the P subbands according to a tree structure to generate a frequency hopping pattern.

Exemplarily, referring to fig. 12(a), a network device transmits SRS resource configuration information #1 and SRS resource configuration information #2 to a terminal. SRS resource configuration information #1 is used to determine SRS resource #1, and SRS resource configuration information #2 is used to determine SRS resource # 2. The number of hopping frequencies determined by SRS resource allocation information #1 and SRS resource allocation information #2 is 2. Therefore, SRS resource #1 may be divided into subband #1 and subband #2 in the frequency domain, and SRS resource #2 may be divided into subband #3 and subband #4 in the frequency domain. The sub-bands #1 to #4 are arranged in a tree structure. Thus, at the first transmission opportunity, the terminal transmits the SRS on subband # 1. In the second transmission opportunity, the terminal transmits the SRS on subband # 3. In a third transmission opportunity, the terminal transmits SRS on subband # 2. At a fourth transmission opportunity, the terminal transmits SRS on subband # 4.

For the related concept of the sending opportunity, reference may be made to the above description, which is not described herein again.

In another possible design, when the number of frequency hopping times corresponding to the M SRS resources is different, the terminal may arrange the P subbands according to a preset rule to generate a frequency hopping pattern. Wherein the preset rule is used for enabling the P sub-bands to be distributed discretely.

Exemplarily, referring to fig. 12(b), the network device transmits SRS resource configuration information #1 and SRS resource configuration information #2 to the terminal. SRS resource configuration information #1 is used to determine SRS resource #1, and SRS resource configuration information #2 is used to determine SRS resource # 2. The number of hopping frequencies determined by SRS resource configuration information #1 is 2. The number of hopping frequencies determined by SRS resource configuration information #2 is 4. SRS resource #1 may be divided in the frequency domain into sub-band #1-1 and sub-band #1-2, and SRS resource #2 may be divided in the frequency domain into sub-band #2-1, sub-band 2-2, sub-band 2-3, and sub-band # 2-4. And the sub-bands are arranged according to a preset rule to generate frequency hopping patterns. Thus, at a first transmission opportunity, the terminal transmits SRS on subband # 1-1; in a second transmission opportunity, the terminal transmits the SRS in the sub-band # 2-1; in a third transmission opportunity, the terminal transmits the SRS in the sub-band # 1-2; in a fourth transmission opportunity, the terminal transmits the SRS in the sub-band # 2-2; in a fifth transmission opportunity, the terminal transmits the SRS in the sub-band # 2-3; in the sixth transmission opportunity, the terminal transmits the SRS in subband # 2-4.

Based on the second mode, K groups of sending opportunities exist in one frequency hopping period to meet preset conditions, any one group of sending opportunities in the K groups of sending opportunities comprises two adjacent sending opportunities, and the preset conditions are as follows: the subbands occupied by the SRSs transmitted at two adjacent transmission occasions respectively belong to different SRS resources in the M SRS resources in the frequency domain, and K is a positive integer greater than or equal to M.

Taking fig. 12(b) as an example, in one frequency hopping period, the SRS transmitted at the first transmission opportunity occupies subband #1-1, and the SRS transmitted at the second transmission opportunity occupies subband #2-1, and since subband #1-1 and subband #2-1 belong to different SRS resources in the frequency domain, the first transmission opportunity and the second transmission opportunity constitute a set of transmission opportunities satisfying a preset condition.

Taking fig. 12(b) as an example, there are 3 sets of transmission opportunities in one hopping period that satisfy the preset condition. The 3 sets of transmission timings are { first transmission timing, second transmission timing }, { second transmission timing, third transmission timing }, and { third transmission timing, fourth transmission timing }, respectively.

It should be understood that, by using the frequency hopping mode of the second mode, the network device can be ensured to quickly acquire channel information in a wider frequency domain, which is beneficial for the network device to quickly acquire channel information in a full bandwidth. Taking fig. 12(b) as an example, the network device obtains the channel information of the subband #1-1 and the subband #2-1 after two frequency hops, and the subband #1-1 and the subband #2-1 are distributed and dispersed over the whole bandwidth, which is beneficial for the network device to estimate the channel information of the whole bandwidth through interpolation or extrapolation.

S205, the network device receives the SRS sent by the terminal on the M SRS resources.

Optionally, when the terminal transmits the SRS in the frequency hopping manner on the M SRS resources, the network device receives, on the M SRS resources, the SRS transmitted in the frequency hopping manner by the terminal. Or, when the terminal transmits the SRS in the non-frequency-hopping manner on the M SRS resources, the network device receives the SRS transmitted in the non-frequency-hopping manner on the M SRS resources.

Optionally, the network device receives the SRS, which is sent by the terminal in the non-frequency hopping manner, on the M SRS resources, and may adopt the following one or two manners.

In a first mode, the network device determines the arrangement sequence of the M SRS resources. And then, the network equipment receives the SRS transmitted by the terminal in a frequency hopping mode on the M SRS resources in sequence according to the arrangement sequence of the M SRS resources.

And secondly, the network equipment determines a frequency hopping pattern according to the M SRS resource configuration information. Then, the network device receives the SRS transmitted by the terminal in a frequency hopping manner on the M SRS resources according to the frequency hopping pattern.

For details of the first and second manners, reference may be made to the related description in step S204, and details are not repeated here.

Based on the technical scheme shown in fig. 10, the terminal transmits SRS on M SRS resources, so that the network device can perform channel estimation on frequency domain resources occupied by the M SRS resources.

The embodiment shown in fig. 5 is advantageous for saving signaling overhead.

Compared with the embodiment shown in fig. 5 in which the SRSs transmitted on the N frequency domain sub-resources all use the same comb, cyclic shift value, and sequence ID, the SRS transmitted on the M SRS resources in the embodiment shown in fig. 9 may use different comb, cyclic shift value, and/or sequence ID.
